When set to ename:VK_FALSE the range of image coordinates is zero to
one.
When pname:unnormalizedCoordinates is ename:VK_TRUE, samplers have the
following requirements:
** pname:minFilter and pname:magFilter must: be equal.
** pname:mipmapMode must: be ename:VK_SAMPLER_MIPMAP_MODE_NEAREST.
** pname:minLod and pname:maxLod must: be zero.
** pname:addressModeU and pname:addressModeV must: each be either
ename:VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_EDGE or
ename:VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_BORDER.
** pname:anisotropyEnable must: be ename:VK_FALSE.
** pname:compareEnable must: be ename:VK_FALSE.
